In this paper, the dielectric absorption power of wood microwave drying is derived from the RC model of wood microwave drying, and the drying mechanism is discussed from the perspective of spectroscopy, the temperature distribution is calculated, the...
Study on microwave drying 2018-10-25 14:11:06
Based on the test results and years of production experience, the microwave output power listed in the microwave drying reference list of some commonly used tree species and sawn timber specifications is proposed. For a channel microwave dryer like Wuxi...
Study on microwave drying of wood 2018-10-25 13:59:50
Wuxi No.2 Furniture Factory developed a wood microwave dryer in May 1977. Through several years of production practice, the technical performance of the microwave drying equipment is basically stable, and the drying production is relatively normal....
Analysis of moisture migration mechanism of wood during microwave drying 2018-10-25 13:50:07
The microwave drying equipment test showed that the temperature distribution in wood was uniform during the microwave vacuum drying process, and there was no fixed distribution pattern of overall internal high, external high and external low or external...
Temperature dependent properties of wood during microwave drying 2018-10-25 13:27:13
It can be said that the microwave radiation power has a significant effect on the temperature variation characteristics of wood. The higher the power is, the faster the heating rate is, and the shorter the isothermal time is. The thicker the sample is, the...
Mechanism of moisture movement in wood during microwave drying 2018-10-25 11:13:54
Abstract: By measuring the internal temperature, pressure and stratified moisture content of wood during microwave drying, the distribution and variation of temperature, vapor pressure and moisture in wood during microwave drying were studied. During the...
Experiment on microwave drying of wood 2018-10-24 17:23:41
According to the sectional density distribution curves of wood specimens in the initial state before drying, during drying and under dry condition, the sectional density distribution along the thickness direction can be obtained by linear interpolation and...
